Starting and stopping CICS

This is information about how CICS starts and stops, the implications of different types of start and stop, and the actions you must take to handle them.

What happens when you start CICS
When you start CICS, you start a process called CICS system initialization. This process must finish before you run any transactions.
Managing CICS shutdown
This section describes how to shut down CICS and processing of system shutdown.
CICS warm-up and cool-down, facilitated by z/OS Workload Manager health service
With z/OS® Workload Manager (z/OS WLM) health service, you can enable CICS to have a warm-up process after the end of system initialization to control flow of work into the region until the region is fully ready to receive work. You can also enable CICS to have a cool-down process before system shutdown to limit flow of work into the region.
